For example, all of the list abstractions (map, filter, reduce, etc.) will copy the array to a new list every time you chain them.
This methods were added to generator recently. So you can avoid copying the array in memory.
All this is also without even getting started on the million JS frameworks and libraries which make it really easy to have vendor lock-in and version lock-in at the same time
In my opinion, it’s also what make JS good. There a package for almost everything.
The API of ListenBrainz is really simple. I built a simple MPV script to send my listenned tracks to ListenBrainz in few hours. It does the job pretty well, and I submitted almost 50K records.
For the moment I didn’t do anything with it, but I know I could someday.
